Windows Vista/7- Dreaded Error 2738 - FIX

Couldn't uninstall, install, or repair, no matter what I did, short of reloading Windows.

Most common fix is to register the vbscript.dll, but this didn't solve it either, even tried to unregister it with the /u switch, same error.

Here's the fix:

1- First try to register the vbscript.dll
A- Click Start "globe"
B- Type in Search programs and files box> cmdcmd.exe should show in list, right click on it and select Run as administrator
C- Make sure your in system32 directory, if your unsure type:
for 32bit OS => cd %windir%\system32
for 64bit OS => cd %windir%\syswow64
2- Now register the dll with this:regsvr32 vbscript.dll
You should receive a massage saying it was successful.

Now try to install or uninstall again.
If you still get error then it's time for a quick regedit:

1- Click Start "globe"
A- Type in Search programs and files box> regeditregedit.exe should show in list, right click on it and select Run as administrator
2- Find this key and delete it:HKEY_CURRENT_USER\SOFTWARE\Classes\CLSID\{ B54F3741-5B07-11CF-A4B0-00AA004A55E8}
Now done with regedit.
3- Register the vbscript.dll as described above.

Now you should be able to install or uninstall.

NOTE: This will also work with VZAccess Manager for RIM, if your getting the same error message.
